This study aims to describe students' mathematical problem-solving abilities based on mathematical dispositions at Riyadlul Mukhlishien Middle School. This type of research used in this research is descriptive qualitative. The research subjects used were 21 students of class VIII A. The data sources of this research are in the form of questionnaires, test descriptions and interviews. The results of the questionnaire were used to classify the level of students' mathematical dispositions. After that, two students from each category of mathematical disposition were selected to be the subject of tests and interviews. The results of tests and interviews of mathematical problem-solving abilities were analyzed based on the mathematical disposition of the students. The results of this study indicate that the mathematical disposition of SMP Riyadlul Mukhlishien students is divided into three categories, high, medium and low. Students who have mathematical problem-solving abilities in the high mathematical disposition category are able to meet the indicators of mathematical problem-solving abilities well and write them down completely. Students who have mathematical problem-solving abilities in the moderate mathematical disposition category are able to meet the indicators of mathematical problem-solving abilities but do not write them down completely. Students who have mathematical problem-solving abilities in the low mathematical disposition category are less able to meet the indicators of mathematical problem-solving abilities because they do not write them down completely and still experience errors in calculations

This study aims to determine the effect of using student worksheet (LKPD) based on the Problem Based Learning model on the mathematical problem solving abilities of students of class VIII SMP Negeri 2 Pangean. This type of research was a quasi-experimental study with a pretest – posttest control group design. The population was all students of SMP Negeri 2 Pangean Indonesia in the 2019/2020 school year. Sampling method was using random sampling technique. Based on the results of data analysis, the posttest mean score in the experimental class was 85.45 and the average value in the control class was 54.5, meaning that the average value of the experimental class was higher than the control class. The two-mean difference test using the t test was significant (2-tailed) 0.000 <α = 0.05, which means that the posttest score of students 'mathematical problem solving abilities was different from the average posttest score of students' mathematical problem solving abilities. which uses scientific learning. So it can be concluded that there is an effect of the Problem Based Learning model on students' mathematical problem solving abilities.

The object was SMPSA on cube and cuboid topic in eighth grade of SMP Negeri 1 Binjai Academic Year 2015/2016.This study consisted of two cycles.  Each cycle had two meetings. SMPSA was tested in the end of cycle. Instrument used to collect data in this research were test and observation sheet. After giving a treatment to students, in the first cycle, the average score of their mathematical problem solving ability was 2.30. Ten of  20 students (50%) obtained score ³ 2.67. The average score of teacher’s activities in observation sheet was 2.66, which classified as good category. The average score of students’ activities in observation sheet was 2.55, which classified as good category. In the second cycle, the average score of mathematical problem solving ability was increased became 3.05 with 18 students (90%) obtained score ³ 2.67. The average score of teacher’s activities in observation sheet was 3.44, which classified as very good category. The average score of students’ activities in observation sheet was 3.22, which classified as very good category. From the result of research, it can be concluded that the implementation of contextual teaching and learning (CTL) approach can improve students’ problem solving ability. The suggestion that given for teachers is to be able to implement contextual teaching and learning (CTL) approach as an alternative in learning process that can improve problem solving ability.Keywords : Contextual Learning, Mathematical Problem solving Ability

Learning in the class must be well planned, one of which to create learning instruments that refer to the curriculum implementation. This research aims to produce mathematics learning instruments (Syllabus, Lesson Plan, and Student workshet) using the problem based learning model in the linear systems with two variables matter. This research is a research and development (R&D) using the 4-D model. The research instrument were an instrument of validity in the form of a validation sheet to assess the validity (syllabus, RPP and LKPD) and practical instruments in the form of a questionnaire for students' responses to LKPD. Validation data analysis results obtained an average value for the syllabus is 3.36 in the category of very valid,  value for the RPP is 3.23 in the category of valid, value for the LKPD is 3.32 in the category very valid. Validation result facts state the syllabus, RPP and LKPD are feasible use.  The results of practicality data analysis of LKPD in small group was 87.01% in the very practical category and the result of practicality data analysis in large group trials was 86.10% in the very practical category. Which means the mathematics learning instruments can improve students’ mathematical problem solving ability and feasible used for students in learning.

<p><em>Problem-solving ability is one of the objectives to be achieved in mathematics. This capability is not only used in solving problems related to the field of mathematics, but can be used in solving the problems faced by students in the day-to-day life. One way to develop this ability in mathematics learning is learning by problem posing approach. This approach gives the opportunity for students to formulate questions that are simpler than the available problems. This research aims is to improve the ability of mathematical problem solving of students of grade VIIA, Junior High School of Muhammadiyah 9 Yogyakarta through learning “problem solving”. This is a classroom action research; with the subject of the research were seventh grade students of Junior High School of Muhammadiyah 9 Yogyakarta.
